The dimensions of a rectangle are -3x - 2 and 10x - 9 The simplified expression for the rectangle's perimeter is 14x – 22
<u>Solution:</u>
Given that dimensions of a rectangle are -3x – 2 and 10x – 9
Let’s say width of the rectangle = w = -3x – 2
And length of the rectangle = l = 10x – 9
<em><u>The formula for perimeter of rectangle is given as:</u></em>
Perimeter of rectangle = 2 (l + w)
By substituting the length and width values we get,
=> Perimeter of rectangle = 2 [(10x – 9 ) + ( -3x – 2 )]
On simplification we get,
= 2 (10x – 9 – 3x – 2 ) = 2 (7x – 11)
=> Perimeter of rectangle = 14x – 22
Hence simplified expression for the rectangle's perimeter having dimensions as -3x - 2 and 10x – 9 is 14x – 22
9 1/3 days
Step-by-step explanation:
- If the total change in the size of the pencil is -7/9 millimeters. Then the actual change itself is 7/9 which is a positive value.
- If each day the pencil changes by 1/12 millimeters, how many 1/12 millimeters are there in 7/9 millimeters. This is a division query;
7/9 ÷ 1/12 = 7/9 * 12/1 = 28/3
= 9 & 1/3 days

Answer:
I hope you got it. I have presented it clearly and stepwise.
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is
The given line passes through the points (0,-20) and (4,10). So, the equation of line is
Subtracting 20 from both sides, we get
The function form is
f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
